Problem wih jabsco toilet

[mjcoon]

I was also puzzled by the comments about the unreliability of the joker valve. We've had boats for quite a few years now and I've never had to replace one. The only time I ever had a problem was when I flushed some dirty cat litter and the valve temporarily stuck open - it took a lot of pumping to clear that!

I guess you hadn't eaten the cat litter first, per usual guidelines...

Quite true! Actually I think the problem was that, being originally desert animals, cat poo is very dry - doesn't mash up on its way through the joker valve in the same way that human poo does... However you look at it, since that event if I ever have to clean the litter tray at sea, it goes directly over the stern, not through the loo!

When Joker valves fail they leak smelly water back into the bowl. The usual cause is that urine reacts with seawater to cause deposition of, mostly, insoluble carbonates, which fill the space behind the valve, distorting the rubber, and on the tricuspid lips, holding them open. If Joker valves are failing frequently it is almost certainly because insufficient flushing is taking place. It is quite difficult to flush through the vertical part of a loop but prolonged flushing is the best remedy.

We often say to newbies, imagine that you have to empty the whole discharge pipe out to the hull, and then some to clean the inside of the pipe.

For the mechanically challenged we say 10 full pumps of water minimum, after you see the last going out the bowl.

I think that some of that (excluding the urine, I trust) might be analogous to the heart valve problem I have just (yesterday) had diagnosed...
